I'm gonna insult you cause im an insecure bitch

So me , my bff , the toxic friend , and my new friend hung out together , and we were enjoying our time but then that mf pointed at me and said " You need to lose weight I'm fat but you're worse " and that bitch just laughed and she kept saying it over and over again every chance she gets .. Lol I was seriously holding back my tears cause i don't wanna be embarrassed and I could tell that my two other friends felt very uncomfortable .... Glad that asshole moved schools .. Who cares if you're smart? If you're an asshole then f*ck you sir/ma'am
